Figure Legend:
TTR data from scans on 100 nm Al films evaporated on Si (circles) and glass (squares) substrates along with the best fit from the Axf model scaled at 400 ps. Using the best fit values of G and Λ2 from the Axf, the 1Dt is calculated and scaled to the data showing that the 1Dt fails to capture some aspects of the data. The thermophysical properties determined from Axf model best fits are G=90 MW m−2 K−1 for the Al/Si interface, Λ=142 W m−1 K−1 for Si, and G=40 MW m−2 K−1 and Λ=1.0 W m−1 K−1 for the glass substrate. The measured thermal conductivity of the glass substrate is lower than that of pure SiO2 since the substrate in this case is a glass microscope slide, so the various impurities will reduce the thermal conductivity below that of pure SiO2.

Figure Legend:
Sensitivities of the Axf as a function of pump-probe delay time for four different Pt films of varying thickness and thermal conductivity. The various conductivities assumed for the Pt films are listed in the figures. Other parameters used for these calculations are GAl/Pt=500 MW m−2 K−1, CPt=2.85 MJ m−3 K−1 , and GPt/Si=140 MW m−2 K−1 . The properties used for the Al film and bulk Si substrate are listed in Table .
